So i am putting a door under an overhang on my trailer, outswing. What type of hinges work or dont work? Are regular door hinges ok? Piano hinge better/worse? Its 1.5in thick. Anyone tried non-mortise hinges? Those were the only ideas i had so far, thanks.

Dan, being that it’s under an overhang , and protected from the weather , it seems almost any hinge would work . Maybe a simple Piano hinge ? That’s what we used on our last two Foamie trailers . Make SURE to get the stainless steel hinge as others will corrode too quickly ... You been to the Ironmongers yet to check out the Gazillion hinges available ?

I used gate hinges to suspend my vertical hatch. I don't have an overhang, so I had to seal the opening between hatch and roof with a waterproof cover. The gate hinges I used were Stanley National (and/or knockoffs from Home Depot and Lowes; no difference in quality that I can see), and I used three to hang the hatch, and three on each of my doors. They support 48 lbs each, are permanently pinned, powder-coated black or stainless (only the Stanleys, I think), have nylon bushings (so they are self-lubricating and noiseless), show no wear after 5.5 years, and are available everywhere (if I ever need a replacement-unlikely).

When I decided on these hinges, I originally bought them for the classic look (like Jeep door hinges), but realized these were even better than I thought, being rust-proof, noiseless and all. I figured on using two for each door, and three for the hatch, but decided on making it three everywhere, for symmetry. With no looseness or slop in their movement, my hatch (weighing about 55 lbs with attached hardware), and my doors (each weighing less than 12 lbs, complete) will never get off-center or sag, since the hinges are rated for much higher loads (48 lbs per hinge).
